iPhone 3G S – what's under the bonnet?


Rapid Repair has dissected the iPhone 3GS and have identified the technology that makes Apple’s new baby the fastest iPhone ever.

First off the processor – the Samsung S5PC100 based on the ARM Cortex A8 design – is much faster than older versions. 600Mhz compared to the iPhone 3G’s 412Mhz.

The 3GS has a PowerVR SGX graphics chip made by Imagination Technologies – far superior to the prior-generation graphics chip in the older models. RAM has been doubled to 256MB.

Apple are promising that the iPhone 3GS will be better, performance wise, to its older siblings in every way. These technical specifications seem to support this promise.

Get your iPhone 3GS direct from Apple or via O2. If you’ve got one already, let us know what you think – is it much faster?

ATI unleashes the Radeon HD 4890


AMD has just dropped us word of their latest graphics card release, the ATI Radeon HD 4890, which they’re claiming is the most powerful graphics processor in the world.

The beast runs at 850MHz, has 1.36 TeraFLOPs of processing power, as well as 1GB of GDDR5 memory and the functionality to cram four of these things in the same machine, using ATI’s Crossfire technology.

It’s notably faster than its predecessor, the HD4870, but slower than the dual core X2 variant. Pricing reflects that, with the card retailing between £185 and £200. It’s not a massive leap, just an evolution of existing cards, but it’s certainly a solid upgrade if you’re running a graphics card that’s a couple of years old.
